I get the message on two systems. However, once booted swap is working
for me:

Title:
  could not mount /dev/mapper/cryptswap1 M for manual S for skip

Status in “cryptsetup” package in Ubuntu:
  Incomplete

Bug description:
  I get the message in the bug summary during the boot process. The boot
  takes quite a long time and also, the Resources tab in the Gnome
  System Monitor reports the swap is not available.

  I am on 12.04, and during installation, I selected the "encrypted
  home" option. Though it is a fresh install, I left my /home partition
  intact, and it dates back to ... I don't even know, maybe 10.04? At
  first I installed Kubuntu, but since then I have changed to Unity and
  I have uninstalled the Kubuntu desktop.

  I am aware of bug #874774, but I felt the need to open a new bug
  report, since even though the fix has supposedly already been released
  for that one, I still experience this problem.
